Question

the surface area of a cube is 294cm^2(i)the length of an edge of tge cube.(ii)the volume of the cube​

Answer 1

Answer:

the edge is 7cm

and volume 343cm³

Step-by-step explanation:

if the surface are of a cube is 294cm²

then

let's consider the edge of the cube is x

then the surface area will be- 6× x²cm².

so

6x²= 294

x²= (294/6)

X²= 49

x=7

so now the volume will be - a³ cm³

= 7³cm³

= 343 cm³
